Hi Yoann and Florent,
I am excited to see some new (corporate) interest because this project
always gets an important boost whenever a user decides to become a
Both Jeroen and I joined a couple of years ago because of a similar
project, so there is definitely a lot of sympathy to your cause (not just
because of the choice of the project ;-))
It could be useful to understand when the internship will start and when
it should be concluded, as well as to have a list of objectives ordered
from high to low priority. This could be very convenient to understand how
we can help to achieve your goals.
We also plan to have a Relax-and-Recover developer meeting in Ghent,
Belgium to discuss a few of the important items we should tackle. Both
discussions and hopefully some implementations will result from this. If
you are interested to join, let me know. We haven't set any dates yet so
we can accomodate to the interest of others if needed.

Both the variety of configurations, as well as better testing, is
something I am personally interested in because of our previous project.
Any help is more than welcome in both areas !

Schlomo Shapiro already answered on this one and I agree with his
assessement. We tend to support both recovery to the exact same system as
well as different hardware.
A functional requirement and a specific use-case for this request could be
useful. For instance, I think some improvement to reporting to the user
that /dev/sda is not the original disk is a welcome addition (and probably
better than just comparing the size). We have the information, so why not
put it to good use ?
I am anticipating great things to come ;-)
